Evaluation of the effect of red cell distribution width on the development of acute renal failure in patients with sepsis.

Objective: Acute kidney injury (AKI) is an important clinical entity that is known to increase mortality in patients with sepsis. Erythrocyte maturation and proliferation are inhibited by pro-inflammatory cytokines; these cytokines exert effects on red cell distribution width (RDW) well. Based on this knowledge; our aim in this study was to evaluate the impact of RDW on acute kidney injury in patients with sepsis. Methods: 120 patients diagnosed with sepsis and admitted to intesive care unit (ICU) and treated between 2009-2013 were retrospectively evaluated. Patients were divided into two groups as follows: group 1 (RDW≥16.8) and group 2 (RDW<16.8). Multiple logistic regression analysis was used to determine the association between RDW and AKI and mortality. Results: There was a statistically significant relationship between AKI and RDW (p<0.001, OR=11.52) but there were no statistically significant relationship between AKI and sex, age, serum lactate levels as well as SOFA score. Also, there were statistically significant relationship between mortality and RDW (p=0.044, OR=5), serum lactate levels (p=0.030) and SOFA score (p<0.001). RDW was found associated with both AKI and mortality. Conclusions: Results suggest that RDW is an important parameter for predicting development of AKI and mortality in ICU patients with sepsis.
